To all whom it 'may concern."

Be it lrnown that l, STANISLAW d'. linien sznwsKr, a citizen of theUnited States, and residing at Detroit, in the county of llayne andState oi Michigan, have invented a new and Tmproved Heater, of which thefollowing is a speeilication.

This invention relates to heaters especially adapted to lreep warm the'engines ot motor vehicles during cold weather as set forth in my PatentNo. 1,007,710, dated November i', 1911, and the object of this inventionis to provide a heater `which will not be extin# guished when thevehicle is passing over rough roads or during stormy weather, and whichwill permit of an easy removal of the burner at all times.

This invention consists, in combination with a coil and a shell aroundit, oli' a base below the shell and which is provided with novel batdeplates to control the currents ot air, ot a novel air inlet chamberextending over one end o1 the base, oit a fiue for excess air extendingup the outside of the shell, of a l' burner below the coil, a burner,and novel means for mounting the burner within the base. 1t furtherconsists in the details et construction illustrated in the accompanyingdrawings and particularly pointed out in the claims. t

Tn the drawings, Figure 1' is a central vertical section oit thisimproved heater. Fig". 2 is a section oi the burner on the line 2--2 o1.lligz l. llig". 0 is a horizontal section through a support .tor thecoils. Fig. i

Similar reference characters reiter to lilre parte throughout theseveral views. y

The shell in which the coils 1 and 2 are mounted is preferably termedolf two metal sheets 3 and t, preferably steel, and a sheet o1 asbestosbetween themu it top plate or diaphragm 5 is perforated to permit theescape oi' burnt gases and may be termed with small pedestals 0 tosupport a coolrine; uten sil it desired. The removable hood is formed oia tapering; body 'l' having a Harige 8 and a. chimney 9. A ring" iscarried by ears 11 on a thinible 12 and supports the cap 13 by means oithe ears 1t.

The coils 1 and 2 are secured at their ends in proper holes in thelittings 15 (llig. 3), held in position in the shell by means of screws16. The inlet pipe 17 and outlet pipe 10 for the water to be heatedconnect into these httings.

' as shown in llig. 5.,

The door is formed oi a sheet oi metal 23 and an asbestos lining 2&1-,secured in po sition by means of the screws The side edges 26 oi thedoor may extend over 'the posts 21, the bottom edge 2l may entend overthe base and the top edge may be folded down over the lining as shown inllig. 1. The burner is mounted on this door and can be slipped into andout ci position as de# sired.

The body B0 oi the burner has a horizon tal bore to receive the needlevalve 31 and has a horizontal discharge orilice 32. l fuel supply pipeconnects to the nipple '33 and the fuel passes through the combinedhlter and storage chamber 341-. This storage i chamber will usuallycontain sutlicient liquid `fuel to leed the Haine while the supply tanlris being reiilled, the l'uel in the supply charnber vaporizingl duringsuch time. The post on the body supports a burner ring 30 having' theusual slots 3l', intalte openingn 38 and passages 39 to permit to burnaround the post and above the body 'l0 ot the burner to heat the postand body.- il delector plate l0 at the top ci" the post causes the llameto pass up between the coils instead oi up through the inner coil. Thetl-shaped mixing,r tube ll2 has a downward extension 113 which catchesthe liquid iuel which may drip from the orilice 32 and con veys it tothe igniter.

The igniter is secured to the base in any' desirable manner and isimormed with a trough t5, an ovcrilow Llt that regulates the height oit'fuel in the trough, air passages Il?, aperi'orated thiinble 4th and aperforated. ring t9. The fuel in this trough may be ignited by insertinga taper or a wire tipped with a ball ofiiber soaked in alcohol throughthe opening in the door shown in liig. et, where a threaded bushing,1receives the plug 51. This plug; may be temporarily removed but must bereplaced to prevent igni tion oi any gas-clone diurnes which might be inthe air oi the room where the burner is used lltl 'tti

lllll ltlli An air chamber fits around a lateral exten# sion of the baseand is preferably no wider than the shell. The free edges of its sides52 are preferably secured to the sides 58 of the extension of the baseby means ofthe screws 54, its top 55 is suiliciently above the bottomofthe base to insure a large quantity of inert air, and its bottom 56 isperforated to admit air. A small cross plate 59 connected to the sides52 may be used to close the space between the bottom 56 and the base ofthe heater. j

The sides 53 of the base preferably converge and are integral with therounded end which leaves a considerable air passage between it and atleast one of the sides or the outer end 58 of the air chamber. 'A crossbar 57 extends between the sides of the base and below it is a box-likecase 60 to receive the U-shaped tube 42. A horironthen bends up to thisease. -A second baille plate 63 extends down from the bottom of theshell at the top of the case 6() on each side of this U-shaped tube tothe bottom of the case 60 and then bends back toward the plate 62 toform an intercepter 64.

A flue or passage 65 is formed by the side plates 66 which arepreferably portions of the shell, as shown in Fig. 4, and the outerplate 67. A passage 68 in the shell just below the top plate 5 permitsthe air which rises in the flue 65 to enter the shell. A second plate 69holds the sheet of asbestos 7 0 in position, which prevents heat passingto the air chamber, thus keeping the flue warm and causing the airtherein to rise.

After the fuel in the igniter trough 45 is burning, it heats the body ofthe burner and vaporizes the fuel which passes to the burner ring and isthere ignited by the flame of the liquid fuel in the trough. Air entersthrough the perforations in the plate 56 and passes up into the airchamber and then down into the base. Some of this air passes between thebaille plates directly te the burner; the remainder is thrown up by theinner edge 7l of the plate 62 and impinges on the plate 63 and passes upthe flue 65 and out through the passage 68 and the perforated top 5 ofthe shell. Any sudden gust or blast of airl entering through the holesin the plate 56 will be cushioned by the air in the air chamber, and ifthe current down into the base is swift, the air will be mostlydeflected to the flue 65. No more air passes down around the deilector64 than is necessary for the burner, and most severe tests have shownthat the flame of the burner cannot be extinguished by high winds or byjars.

I claim 1. In a heater, the combination of a cylindrical shell, aheating coil therein, a burner below the coil, a base upon one end ofwhich the shell is mounted and provided with a lateral extension, a doorat one end of the heater and means to secure the burner to said door, anair chamber slidable onto the extension of said base and spacedtherefrom at at least one side and having a perforated lower end and aclosed upper end, baille plates mounted within the base, and a passagefor excess air extending up from said base along the shell.

baille plates mounted within the base, and a passage for excess airextending up from said base along the shell, said shell being formedwith an opening just below its perforated top to communicate with saidpassage.

3. In a heater, the combination of a shell and a coil therein, a base towhich the shell is connected and having a lateral extension, an airchamber fitting over said extension and having a side spaced therefromand provided with a closed top, baffle plates within the base, and apassage for excess air extending up from the base alon the shell.

4. In a heater, the combination of a shell and a base therefor having alateral extension, an air chamber mounted around said extension andhaving at least one side spaced therefrom, said air chamber having aclosed top and aperforated lower end, two baille plates within the baseadapted to deflect upwardly the air entering the extension of the base,and a flue extending up from the base to carry away the upwardlydeflected air.

5. In a heater, the comblnation of a shell and a coil therein, a base towhich the shell `is connected and a burner within the base below' thecoil, an air chamber adjacent the base and having a side spacedtherefrom, the top of the air chamber and the bottom of the base beingclosed, means to obstruct the flow of air within the base, and a passagefor excess air extending up from the base along the shell.
